terrestrial solar power

Solar power which is generated on land/the Earth as opposed to space based solar power. Terrestrial solar power is a predictably intermittent energy source, meaning that whilst solar power is not available at all times, we can predict with a very good degree of accuracy when it will and will not be available. Extraterrestrial solar power is solar power generated in space / not on Earth. In space, collection of the Sun's energy is unaffected by the various obstructions which reduce efficiency or capacities of Earth surface solar power collection. Source: (in part) Wikipedia.
